These four chapters tell the story of God’s prophet Jonah (who attentive Bible students know from 2 kings 14:25:
He restored the border of Israel from Lebo-hamath as far as the Sea of the Arabah, according to the word of the LORD, the God of Israel, which he spoke by his servant Jonah son of Amittai, the prophet, who was from Gath-hepher.
This true prophet runs away from God, says a long prayer inside a fish, preaches a five word sermon and converts the capital of an unusually brutal empire, and then tells God off grumpily! The story of Jonah is told in ways that cause us to laugh, or at least smile. This book is funny from beginning to end – which is different from other Bible books even though many of them contain humour see the podcasts here.
What’s going on? and Why’d he do it?
There are a number of podasts if you want more on Jonah, or I have some study notes on the book of Jonah (not yet quite finished, or a longer lecture on Jonah.
